False, the chemical make up hardly ever changes, The physical property is the one that changes
Answer:
R = 0 and no population growth.
Explanation:
Birth rate may be defined as the growth of individual per thousand and death rate determines the death of individual per thousand in a year. The birth and death changes the population dynamics.
The growth rate depends on both the factors that are birth rate and death rate. Here, the birth rate is balanced or equal that replace the offspring father. The change in the population growth is same and the birth and replacement almost cancel out each other. In this case, the birth rate is zero and population do not grow.
Thus, the answer is R = 0 and no population growth.
Answer:
Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).
Explanation:
Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.
During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.
With respect to the law of conservation of energy, it is necessary to consider:
- In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
- Energy in an isolated system does not vary, unless it comes into contact with another system.
- The amount of energy that is absorbed and obtained is equivalent.
In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.
Regarding other options:
<em> 1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>
<em> 3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>
<em> 4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>

Receptors which provide animals with information from the external environment are located in ears, tongue, eyes, and the nose. These are all receptors that can be found in our sensory organs and provide us with feedback from our nearby environment and the stimuli on which we should be alerted towards.
